2000 Ford Explorer Engine Chirping

There is a high pitched chirping noise coming from front of engine. Have changed the serpentine belt and idle pullys already, what else could it be? Read something about a "camshaft position sensor&quot. Could it be that? It idles rough most of the time.

Did you replace the belt tensionier? Try this test. Start the car, open the hood, and pour a small amount of water on the belt to see if the noise changes or stops. Make sure to wear old clothes and have eye protection because there is a good chance the water will spray back at you.
